This seed spawns you in the swamp next to a set of extreme hills. Nearby underground you can find an abandoned mineshaft to explore. Then not too far away in the middle of a roofed forest, you can find a village. Start by turning around and going to the cave in the middle of the trees at -9 / 61 / 203.
This seed spawns you in a forest, but not far away you can find taiga and extreme hills biomes. Better yet, the taiga contains a village with a blacksmith shop. This seed keeps on giving with a ravine next to the village, and llamas in the extreme hills not far away.
This seed has two villages close to each other that both contain blacksmith shops. To make it even better, one village is next to a ravine that contains a fossil. Fossils are rare structures that only show up in a couple of biomes.
This seed spawns you in a taiga with a village nearby. On the opposite side of the village where you spawned, you can find a ravine with an abandoned mineshaft. In the mineshaft, there are a dungeon and a chest minecart with a diamond. This seed seems to just keep getting better the deeper you go.
It’s cool to find a village, desert temple, and ravine near each other, but on this seed, they’re all right on top of one another. When you spawn you’ll be in a plains biome, but going left will take you into the desert. At 278 / 64 / 196 you’ll find all of the structures tangled together.
